Abstract: Provided are an ophthalmic lens and a technique related thereto, the ophthalmic lens including two lens elements 1 and 2 having powers with different signs, in which when the Abbe number (e-line reference) of the lens element 1 having a power with a smaller absolute value is νe1, and the Abbe number (e-line reference) of the other lens element 2 is νe2, Formula 1 below is satisfied, and νe1 PgF′2  (Formula 2).

Abstract: A technology that makes a change in the amount of aberration in a spectacle lens worn by wearer relative to a change in at least one of the aberration in the eye or spectacle lens. A method for designing a spectacle lens wherein, when a degree of change caused by a physical feature of wearer in at least one of an aberration distribution of an eye of wearer and an aberration distribution of a spectacle lens worn by the wearer is large, a spectacle lens that has an aberration distribution of which rotational asymmetry is weak in a region having a predetermined width and a center at any point on a main meridian of the spectacle lens is obtained as a design solution, and when the degree of the change is small, a spectacle lens of which rotational asymmetry is strong in the region is obtained as a design solution.

Abstract: A spectacle lens according to the first embodiment of the present disclosure includes: a lens body; and a contrast adjustment section provided on or in the lens body and including a dot-portion group in which dot portions are arranged, wherein the arrangement of the dot portions is non-uniform. A spectacle lens according to the second embodiment of the present disclosure includes: a lens body; and a contrast adjustment section provided on or in the lens body and including a dot-portion group in which dot portions are arranged, wherein the dot-portion group includes dot portions each having an aspect ratio, which is the ratio of the length in the short-axis direction to the length in the long-axis direction in the plan-view shape, of less than 1.
